What number of the month are we on? All months have 30 or 31 days, except for February which has 28 days (29 in a leap year). Every fourth year, the month of February has 29 days instead of 28. This year is called a “leap year” and the 29th day of February is a […]
Which fluid is present in ear?
Which fluid is present in ear? Endolymph is the fluid contained in the membranous labyrinth of the inner ear. The major cation in endolymph is potassium, with the values of sodium and potassium concentration in the endolymph being 0.91 mM and 154 mM, respectively. It is also called Scarpa’s fluid, after Antonio Scarpa. What does […]
What is steam reforming process?
What is steam reforming process? Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen production. The reaction is strongly endothermic (consumes heat, ΔHr = 206 kJ/mol). What is […]

What are the four types of causal relationship? If a relationship is causal, four types of causal relationships are possible: (1) necessary and sufficient; (2) necessary, but not sufficient; (3) sufficient, but not necessary; and (4) neither sufficient nor necessary. What is meant by causal relationship? A causal relationship exists when one variable in […]
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet?
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet? Metamorphic rocks form when high temperature and pressure alter existing igneous and sedimentary rocks. Metamorphic rocks can also be formed from other metamorphic rocks. Rock changes in Metamorphic Rocks. Rock changes into metamorphic form when it experiences intense […]
Why is latitude 180 degrees?
Why is latitude 180 degrees? “Longitude” goes 360 degrees, 180 East to 180 West, to cover the entire 360 degrees around the equator. But if latitude did the same thing, every point on the earth would be covered twice! So latitude only has to cover 180 degrees, from the north pole to the south pole. […]
What is the critical angle of ice?
What is the critical angle of ice? 49.8 degrees How do you find the critical angle in Snell’s law? The critical angle can be calculated from Snell’s law by setting the refraction angle equal to 90°. For any angle of incidence less than the critical angle, part of the incident light will be transmitted and […]
How does Mildred die?
How does Mildred die? Montag finds Mildred passed out, having overdosed on thirty plus sleeping pills. Her stomach is pumped and her blood re-circulated. The next morning she doesn’t remember any of it. Why can’t Montag run away? Physically, Montag is unable to run as fast as he would like because of his confrontation with […]
Why do clothes get wet?
Why do clothes get wet? When light strikes any surface, some of it is reflected back into our eyes. But damp clothes have a thin layer of water on their surface (held in place by the material’s roughness), which leads to more of the reflected light rays being bent – ‘refracted’ – off-course. When a […]
